This scatter plot visualizes the relationship between automobile characteristics, with miles per gallon on the x-axis, horsepower on the y-axis, origin indicated by color, and weight mapped to point size. The chart uses tooltips to display vehicle names and detailed specifications. The visualization is built using the Vega-Lite API in conjunction with D3.js for data loading and Vega Tooltip for interactive hover effects. Data comes from the UCI Machine Learning Repository's auto-mpg dataset, converted from CSV format. The chart adapts to window resizing via a ResizeObserver and features customized styling for improved readability.
